WordPress:tax_query使用OR运算符的多个术语 [英] Wordpress: tax_query multiple terms using OR operator

问题描述

简单查询，但由于某些原因未显示正确的帖子，尝试显示带有每月待办事项列表字词的帖子，如果没有结果，则显示与社区相关的帖子-事件的期限.有什么建议吗?

Simple query but for some reason is not displaying the correct posts, trying to display a post with the monthly-to-do-list term, if no results then display a post with the community-events' term. Any suggestions?

$todo_args = array(
   'cat' => $my_category_id,
   'posts_per_page' => 1,
   'tax_query' => array(
        'relation' => 'OR',
            array(
               'taxonomy' => 'postkicker',
                'field'    => 'slug',
                'terms'    => 'monthly-to-do-list',
                ),
            array(
                'taxonomy' => 'postkicker',
                'field'    => 'slug',
                'terms'    => 'community-events',
                ),
            ),
    'orderby' => 'date',
    'order' => 'DESC'
);

推荐答案

尝试添加数组并使它像这样:

try adding array and make it like this :

$todo_args = array(
   'cat' => $my_category_id,
   'posts_per_page' => 1,
   'tax_query' => array(
        'relation' => 'OR',
            array(
               'taxonomy' => 'postkicker',
                'field'    => 'slug',
                'terms'    => array('monthly-to-do-list'),
                ),
            array(
                'taxonomy' => 'postkicker',
                'field'    => 'slug',
                'terms'    => array('community-events'),
                ),
            ),
    'orderby' => 'date',
    'order' => 'DESC'
);

您可能会注意到术语是复数形式，并且您还可以像这样简化查询:

As you may notice terms is plural and you may also simplify your query like this :

$todo_args = array(
   'cat' => $my_category_id,
   'posts_per_page' => 1,
   'tax_query' => array(
            array(
               'taxonomy' => 'postkicker',
                'field'    => 'slug',
                'terms'    => array('monthly-to-do-list','community-events'),
                ),
            ),
    'orderby' => 'date',
    'order' => 'DESC'
);
